What is an ulcer?
Imagine the inside of your stomach or intestine is like the wall of a house.
- An ulcer is like a hole in that wall – the injury goes deep, beyond the surface.
- An erosion is a scratch that stays more on the surface and doesn’t go as deep.
How common is it?
- In East Africa, around 15% of people have peptic ulcer disease – that’s about 1 in every 7 people.
- Both stomach and duodenal ulcers are frequent, with duodenal ulcers often more common.
- The duodenum is the first part of the small intestine, directly after the stomach.
- It’s about 20–25 cm long (around 10 inches).
- Shaped like a C or horseshoe.
- It wraps around the head of the pancreas.
- It has four parts: the superior, descending, horizontal, and ascending segments.
- This is where most chemical digestion begins:
- Stomach acid mixes with food (chyme).
- Bile from the liver/gallbladder helps digest fats.
- Pancreatic juice (enzymes + bicarbonate) helps break down carbs, proteins, and fats, and neutralises acid.bicarbonate) helps break down carbs, proteins, and fats, and neutralises
- Ulcers affect men and women, though duodenal ulcers tend to be a bit more frequent in men.
What causes ulcers?
- Bacteria – Helicobacter pylori
-
- Lives in the stomach lining.
- Found in most duodenal ulcers and many stomach ulcers.
- Medicines – especially painkillers
- NSAIDs (like ibuprofen, aspirin, diclofenac).
- Risk is even higher if combined with cortisone tablets.
- Other risks: Smoking, alcohol, stress , age over 65, chronic illnesses (e.g., kidney disease).
- Rare causes: Hormone problems (overactive parathyroid), very high acid production (Zollinger-Ellison syndrome), severe illness or major surgery (“stress ulcers”).
What’s happening inside the stomach?
- The stomach makes acid to digest food but also protects itself with mucus and good blood flow.
- Ulcers develop when the balance is broken:
- H. pylori → increases acid + weakens mucus.
- NSAIDs → block protective prostaglandins.
What are the symptoms?
- Burning or gnawing pain in the upper belly.
- Pain improves with food (duodenal ulcer).
- Pain worsens right after food (stomach ulcer).
- Indigestion, bloating, nausea.
- Serious signs: vomiting blood, black stools.
- Sometimes no symptoms until complications.
How are ulcers diagnosed?
- Stomach endoscopy allows doctors to see inside and evaluate the stomach.
- Biopsies: check for H. pylori and rule out cancer (important for stomach ulcers).
- Blood or stool tests can also detect H. pylori.
How are ulcers treated?
- If caused by H. pylori: Antibiotics + acid blocker (PPI) for 1–2 weeks → “eradication therapy”.
- If caused by medicines: Stop/reduce painkillers, use safer alternatives, take PPIs.
- General treatment: PPIs for 4–8 weeks, avoid smoking and excess alcohol.
- If bleeding: Doctors stop it during endoscopy (clips, injections). Surgery is rare.
Key takeaways for everyday life
- Around 1 in 7 people in East Africa may have an ulcer.
- Most ulcers heal with the right treatment.
- Always test for H. pylori if you have an ulcer.
- Never ignore black stools, vomiting blood, or sudden severe stomach pain → hospital immediately!
- Don’t overuse painkillers like ibuprofen or aspirin. If needed long-term, ask your doctor about protection with PPIs.
